Symptoms

Customer has integrated Oracle Identity Manager (OIM) with Oracle Identity Cloud Services (IDCS).

On running the IDCS Group Lookup Reconciliation Schedule Job the job fails with the following Null Pointer Exception (NPE):

 

[2018-07-16T11:29:54.960-03:00] [servername] [ERROR] [] [ORG.IDENTITYCONNECTORS.RESTCOMMON.UTILS.RESTCOMMONUTILS] [tid: tid] [userId: oiminternal] [ecid: ECID] [APP: oim#11.1.2.0.0] org.identityconnectors.restcommon.utils.RESTCommonUtils : checkStatus : Description not available for received status code.302

If we look at the above log we can see before the Null Pointer Exception (NPE) the following error:

checkStatus : Description not available for received status code.302

To get more information we need to set the connector in trace:32  mode following the steps in the documentation that can be found here https://docs.oracle.com/cd/E22999_01/doc.111/e71438/GUID-2E4BD7FB-599F-4442-98E0-672AB871B07A.htm#GUID-7F3EC1A0-88B0-42F8-A1EB-333C4B1F3022

After enabling the connector on trace:32 mode running the schedule job shows the following:

 

INFO: oracle.iam.connectors.icfcommon.ConnectorFactory$ConnectorConfigurator : configure : Setting [host] to [https://myservices-url.console.oraclecloud.com/mycloud/cloudportal/dashboard]
...
INFO: org.identityconnectors.restcommon.ClientHandler : executeRequest : Making a 'POST' call using the URL 'https://myservices-url.console.oraclecloud.com/mycloud/cloudportal/dashboard'
INFO: org.identityconnectors.restcommon.utils.RESTCommonUtils : checkStatus : REST call Status : HTTP/1.1 302 Moved Temporarily

 

The IDCS connector is a REST connector and as such before performing anything it tries to get a valid token to access IDCS.

From the above logs we can clearly see that we are not trying to reach a token endpoint but instead the myservices login page that redirects us to the IDCS login page (HTTP code 302)
